The most unrealistic thing about Idiocracy is the fact that the president faced a problem that he recognized he was not smart enough to solve. So he listened to the smartest people in the room. We could be facing a dinosaurs era ending style meteor that threatens to kill all life on earth. I would fully assume trump would come up with a plan all on his own. A plan that a 5 year old could poke holes in. The kind of plan that an eyeroll isn't enough, so your eyes themselves groan. Yet nobody will tell him no. At no point will he seek out the help of a mental superior, despite being surrounded by them anywhere he's ever been. And we all die instead of listening to the scientists that would actually formulate a plan that has at least a chance of working.

Oh, and also the citizens in that movie didn't hate each other. They were all too stupid to get along, but it's only their stupidity that causes a divide. They all think they're doing the right thing, and being good people. I cannot in my life imagine the left or the right looking at the other as good people.
